So Injustice: Gods Among Us is a game I am certainly interested in purchasing.  However, I have a bit of a dilemma: I don't know if I should get it for PS3 or Wii U!  The PS3 version will likely have a bigger online community and trophies, but the Wii U version allows you to play the game entirely on the GamePad, which is awesome.  Which version do I buy??  Gah!

Anyone have it yet?  And if so, which system?
